Rake: How to specify that a task has multiple dependencies?

Question

I would like to specify that

:output_core depends on :build_core
:build_extension depends on :build_core
:output_extension depends on :build_extension and :output_core

How would I specify that last one? That in order to run the :output_extensions tasks both :build_extensions and :output_core must have completed?

Answer 1

You specify them with an array:

task :output_extension => [:build_extension, :output_core]
